  1. 2. A line segment between two vertices in a graph (graph theory) or geometric shape..
  2. 3. The symbol representing an nth root,.
  3. 7. A number that is added to another number
  4. 9. 1. A unit of angle, commonly representing one-ninetieth of a right angle.
  5. 10. The deviation from being perfectly circular.
  6. 11. The locus of a point on the circumference of a circle rolling inside of another circle.
  7. 13. A method of inference which attempts to "justify" conclusions by applying rules of inference on the premises of the argument and other such conclusions.
  8. 15. A type of discontinuity, where the hole is a point whose inclusion into the curve would make the curve continuous.
  9. 16. Also known as extraction, the process of finding a root of a number. The opposite process is called involution.
  10. 17. An equivalence relation indicating two mathematical sentences to be necessary and sufficient conditon of each other.
  11. 19. The centre of a circle which goes through all vertices of a triangle.
  12. 21. A controlled process for making observations and gathering data.
  13. 22. A beam or such similar structures which is anchored at only one end such that it resists rotation under load.
  14. 24. An unproven (but also not disproven) assertion considered/assumed/proposed to be true.
  15. 25. Rewriting a mathematical expression in an equivalent form that is considered to be longer or more complicated
  16. 27. A measure of angle which is the ratio of the arc length to the radius formed by a circular arc with the angle.
  17. 28. The condition of an expression of 2 variables that is linear while considering individually each variable (while the other variable is fixed.)

  1. 1. An SI derived unit of radioacitivity denoted by the symbol Bq.
  2. 4. The segment of the perpendicular bisector of a side of a regular polygon that runs between the centre and the side.
  3. 5. A surface formed by the rotation of a catenary.
  4. 6. A particular unit within a set of units of the same type. (e.g. CMwithin the set of units for lengths.)
  5. 8. The process of splitting a mathematical object into two or more objects of the same type, such as fractions, functions or matrices.
  6. 12. A branch of mathematics, the study of (infinitely many) infinitesimalquantities (which may be changing).
  7. 13. A value under which a whole number of tenths of data fall.
  8. 14. Also known as indefinite integration
  9. 17. A plane figure with 2 right angles.
  10. 18. A measure of how little an approximation deviates from the true value
  11. 20. An informal name for symbol ∩, used to denote intersection of sets that is easier to say than the polysyllabic "intersection".
  12. 23. A polynomial with two terms.
  13. 26. A six-sided polygon.
